TECHNICAL FIELD

The present invention relates to the field of two-wheel balancingscooters, and more particularly to a self-balancing scooter.

BACKGROUND

A self-balancing scooter, also called as a somatosensory scooter and athought scooter, has an operation principle based on a basic principleof “dynamic stabilization”, detects the change of scooter body attitudesthrough a gyroscope and an acceleration sensor inside a scooter body,and accurately drives a motor to perform corresponding regulationthrough a servo control system so as to keep balance of a system.

Existing self-balancing scooters are generally classified into twotypes. The first type is as follows: the scooter body has an operatinglever. A user stands on a pedal platform of the self-balancing scooterto operate the operating lever so as to advance, withdraw and stop. Suchcontrol is also called as “hand control”. The other type is as follows:the scooter body is composed of two portions. A left portion and a rightportion realize mutual rotation through a rotating mechanism, so as torealize “foot control”. See a self-balancing swing scooter of a Chineseinvention patent with a publication number CN104029769A (publicationdate: 20140910). According to the description and drawings, a scooterbody structure of the self-balancing scooter is mainly composed of anupper cover, an inner cover and a lower cover. A battery, a controllerand the like are installed and fixed between the upper cover and theinner cover. The lower cover plays the roles of limiting and closing.Because the battery, the controller and the like have large volume andheavy weight, the lower cover needs to be made thick so as to betterlimit and fix the battery, the controller and other devices. However,too thick lower cover greatly increases overall weight of theself-balancing scooter, bringing inconvenience for use and inconveniencefor carrying.

The present invention will be further described below in combinationwith accompanying drawings and preferred embodiments.

A self-balancing scooter 10 in an embodiment of the present invention isdescribed below by referring to FIG. 1 to FIG. 8.

As shown in FIG. 1 to FIG. 8, the self-balancing scooter 10 in thepresent embodiment comprises a scooter body 100, wheels 200, a drivingmotor for driving the wheels, a power supply 300 for providing power, acircuit board 400 provided with a sensor, a controller 500 and a lightemitting lamp electrically connected to the power supply. The controlleris electrically connected to the circuit board, the power supply and thedriving motor respectively. The scooter body 100 comprises:

an upper shell 110 comprising a first upper shell 111 and a second uppershell 112 disposed symmetrically and provided with pedal holes 113respectively;

two pedals 140 disposed in the pedal holes 113 of the first upper shell111 and the second upper shell 112 respectively;

a middle shell 120 comprising a first middle shell 121 and a secondmiddle shell 122 disposed symmetrically and rotatable mutually;

a lower shell 130 comprising a first lower shell 131 and a second lowershell 132 disposed symmetrically, wherein the middle shell is locatedbetween the upper shell and the lower shell; and

a lampshade 150 sleeved around the light emitting lamp. The lampshade150 is provided with at least two spaced lamp strips 154 fortransmitting light. Correspondingly, lamp holes 114 for placing the lampstrips are formed in the scooter body. The quantity of the lamp holes114 is identical with the quantity of the lamp strips 154.

The wheels 200 are provided with rotating shafts 210. The two wheels 200are respectively fixed to both sides of the middle shell through therotating shafts 210, and are rotatable around the middle shell.Specifically, the self-balancing scooter 10 further comprises two fixingblocks 220 used to limit the two rotating shafts 210 respectively.Rotating shaft grooves used to place the rotating shafts are formed inthe middles of the fixing blocks 220, to facilitate rotation of therotating shafts in the rotating shaft grooves of the fixing blocks.Moreover, the fixing blocks are installed and fixed to the middle shellthrough a plurality of screws, thereby ensuring firm fixation andconvenient realization.

Thus, the scooter body 100 of the present embodiment has at least twolamp holes 114 when one lampshade 150 is installed and fixed on thescooter body 100. Compared with a structure in which one lamp hole 114is formed to match with one lampshade 150, the present invention uses atleast two lamp holes to place the lamp strips so that the size of asingle lamp hole is decreased. In this way, at least two lamp holes arematched with the lamp strips. Thus, at least two lamp holes share anacting force used to install and fix the lampshade. Further, matchingbetween a single lamp strip and a single lamp hole is tight. At leasttwo lamp holes and lamp strips are fixed tightly, so that the lampshadeis installed and fixed on the scooter body more firmly and is difficultto swing.

The lamp strips 154 are convex strip-shaped structures of the lampshade150. The lamp holes 114 are configured to adapt to sizes of the lampstrips 154. The lamp strips are configured into the convex strip-shapedstructures to facilitate disposal of the lamp holes with thestrip-shaped structures. In this way, the lamp strips of thestrip-shaped structures and the lamp holes of the strip-shapedstructures are conveniently installed and matched. In addition, amatching and limiting effect of the lamp strips of the strip-shapedstructures and the lamp holes of the strip-shaped structures is good, sothat the lampshade has a better fixed connection and tightening effectfor the upper shell and the lower shell. For those skilled in the art,the lamp strips in the present embodiment can also be configured intoother structures. For example, the lamp strips are configured into arcstructures, and the lamp holes are also configured into arc structures.

Chamfers are formed at tops of the lamp strips 154. The chamfers areformed at the tops of the lamp strips so that the lamp strips areconveniently inserted into the lamp holes.

Further, sizes of the lamp strips 154 from the tops to roots aregradually increased. The sizes of the roots of the lamp strips 154 adaptto the sizes of the lamp holes. The lamp strips are more convenientlyinserted into the lamp holes. Connection between the lamp strips and thelamp holes is tight, so as to avoid generating a clearance.

In a preferred solution of the present embodiment, the upper shell 110is provided with lamp holes 114 for placing one or at least two lampstrips 154. The lower shell 130 is provided with lamp holes for placingone or at least two lamp strips. The sum of the lamp holes of the uppershell and the lamp holes of the lower shell is identical with thequantity of the lamp strips. The lamp holes are respectively formed inthe upper shell and the lower shell in the present embodiment. Thus,when a single lampshade is fixed, the lamp strips on the singlelampshade are simultaneously placed into the lamp holes of the uppershell and the lamp holes of the lower shell. In this way, the lampshadeplays a role of connecting the upper shell and the lower shell, so thatconnection between the upper shell and the lower shell is tighter andfixation is more firm.

In the present embodiment, as shown in FIG. 4, the lampshade 150comprises a first plate 151, a second plate 152 and an angle portion 153located between the first plate 151 and the second plate 152. An angleof the angle portion 153 is smaller than 180 degrees and greater than 90degrees. The lamp strips 154 are located on the first plate 151 and thesecond plate 152. The lamp strips 154 on the first plate 151 are placedin the lamp holes of the upper shell 110. The lamp strips on the secondplate 152 are placed in the lamp holes of the lower shell 130. This is aspecific structure for arrangement of the lampshade in the presentinvention. Such arrangement enables intensity of the lampshade to belarge. Moreover, when the upper shell is connected to the lower shell ina matching manner, a radian is formed between the upper shell and thelower shell. In the present invention, the lampshade is configured intoan integral structure suitable for connection between the upper shelland the lower shell in a matching manner. Thus, the lampshade isconveniently connected to the upper shell and the lower shellrespectively in a matching manner. When connected to the upper shell andthe lower shell respectively in a matching manner, the lampshade istightly matched and the fixed connection effect is better.

Specifically, at least two lamp strips 154 are located on the firstplate 151. At least two lamp strips 154 are located on the second plate152. A larger quantity of the lamp strips realizes greater bearingcapacity, so that the connection effect between the upper shell and thelower shell is better. This is a preferred solution of the presentembodiment. Of course, in the present embodiment, one lamp strip may bedisposed on the first plate, and one lamp strip may be disposed on thesecond plate. In addition, the quantity of the lamp strips on the firstplate is identical with the quantity of the lamp strips on the secondplate. Because the quantity of the lamp strips disposed on the firstplate is identical with the quantity of the lamp strips disposed on thesecond plate, the upper shell and the lower shell bear uniform stress.

In the present embodiment, the lamp strips on the first plate and thelamp strips on the second plate are disposed symmetrically. Symmetricalarrangement ensures uniform stress. This is a preferred solution fordisposing the lamp strips in the present embodiment. Of course, forthose skilled in the art, the lamp strips can also be configured to beasymmetrical.

In the present embodiment, one end of the angle portion between thefirst plate and the second plate protrudes outwards to form a convexportion 155, and the other end sinks inwards to form a concave portion156. The other end is close to a middle of the scooter body. The convexend of the lampshade is larger than the other end, and is graduallydecreased. Because the middle of the scooter body is smaller than thesizes of both sides of the scooter body, such arrangement ensures thatthe lampshade is disposed to match with a scooter body structure and thelampshade has a better connection effect for the upper shell and thelower shell and larger intensity. This is a preferred solution fordisposing the lampshade structure in the present embodiment. Of course,for those skilled in the art, the lampshade can also be configured intoother structures. For example, both ends of the lampshade are configuredinto parallel structures with equal sizes.

An angle greater than or equal to 0 degree and smaller than 90 degreesis formed between the lamp strips 154 and the angle portion 153. This isa specific manner for disposing the lamp strips. Of course, the lampstrips can also be configured to be parallel to the angle portion.

Further, a length of the lamp strips on the first plate 151 is graduallyincreased from the convex end to the other end. A length of the lampstrips on the second plate 152 is gradually decreased from the convexend to the other end. A change amplitude of the length of the lampstrips on the second plate is greater than a change amplitude of thelength of the lamp strips on the first plate. The upper shell is locatedin a position at the top of the scooter body. Because the pedal holesare formed in the middles of the first upper shell and the second uppershell of the upper shell, the lamp holes in the present invention areformed at edges of the first upper shell or/and the second upper shell.The change of the edge of the upper shell is small. In this way, achange amplitude of the length of the lamp holes formed in the uppershell is small. Meanwhile, the lower shell is located at the bottom ofthe scooter body. The middles of the first lower shell and the secondlower shell of the lower shell are used to place the power supply, thecontroller and other devices. The middles protrude greatly outwards, sothat the lamp holes with small length are disposed in the middle of thelower shell close to the scooter body and the lamp holes with largelength in the lamp holes of the lower shell are conveniently presented,so that a user sees light emitted from the lamp holes.

A size of one end, close to the angle portion 153, of the lamp strips154 is larger than a size of the other end of the lamp strips. Thelampshade in the present embodiment connects the upper shell and thelower shell through the lamp strips on the first plate and the secondplate. When an outward tension is applied between the upper shell andthe lower shell, one end, close to the angle portion, of the lamp stripsis stressed. However, in the present embodiment, one end close to theangle portion is configured to be larger than the other end of the lampstrips. Thus, the lamp strips on the stressed end are larger, havestronger bearing capacity and realize better connection between theupper shell and the lower shell. This is a preferred solution fordisposing the lamp strips. Of course, for those skilled in the art, inthe present embodiment, the lamp strips can also be configured intoother structures. For example, both ends of the lamp strips areconfigured into structures with equal sizes.

In the present embodiment, two light emitting lamps are disposed and arerespectively installed and fixed on two light emitting lamp plates 11.The light emitting lamp plates 11 are electrically connected to thepower supply 300 and the circuit board 400 respectively.Correspondingly, two lampshades 150 are also disposed. The twolampshades 150 are respectively matched with the two light emittinglamps. Specifically, the two lampshades 150 respectively cover outerportions of the two light emitting lamp plates 11, and play roles oflimiting and protecting the light emitting lamp plates. In addition, thetwo lampshades in the present embodiment are symmetrically disposed, andthe two light emitting lamp plates are symmetrically disposed. Moreover,the two lampshades are disposed at the same side of the scooter body,and located on both sides of the middle of the scooter body. It shouldbe indicated that for those skilled in the art, the quantity of thelight emitting lamps and the quantity of the lampshades disposed in thepresent embodiment are not limited to two. For example, only one lightemitting lamp and only one lampshade are disposed. For example, threelight emitting lamps and three lampshades are disposed.

In the present embodiment, the light emitting lamps are LED lamps.Namely, the LED lamps are disposed on the light emitting lamp plates 11,and have long life and good effect.

In the present embodiment, the light emitting lamps are strip-shapedstructures. Specifically, the light emitting lamp plates arestrip-shaped structures. The light emitting lamp plates 11 with thestrip-shaped structures are conveniently installed and fixed into thescooter body. Of course, the light emitting lamps in the presentembodiment can also be directly provided with one or more lamp beads.The lamp beads are installed and fixed into the lamp strips.

In the present embodiment, the light emitting lamps are installed andfixed into the scooter body through screws. Specifically, the lightemitting lamp plates 11 are fixed into the scooter body through thescrews. The screws are firm in fixation and convenient in installation,fixation and disassembly.

In the present embodiment, the driving motors are hub motors. Two hubmotors are respectively disposed in the two wheels 200. However, in thepresent embodiment, the driving motors can also be disposed in thescooter body, and realize driving connection with the wheels through therotating shafts.

In the present embodiment, the first middle shell 121 and the secondmiddle shell 122 are fixedly connected through the rotating mechanism600. The first middle shell 121 and the second middle shell 122 realizemutual rotation through the rotating mechanism.

The rotating mechanism 600 is disposed in a middle position of aconnection position between the first middle shell and the second middleshell. The rotating mechanism comprises a shaft sleeve 610, two bearings620 and a limiting shaft 630. Both ends of the shaft sleeve arerespectively fixed to inner ends of the first middle shell and thesecond middle shell. The two bearings 620 are fixed to the shaft sleeve610 and fixed between the first middle shell and the second middle shellthrough a clamp spring. In this way, the first middle shell and thesecond middle shell of the middle shell are rotatable under the matchingof the rotating mechanism 600. In addition, the limiting shaft 630 playsthe roles of limiting and fixation.

It should be indicated that the rotating mechanism, the circuit boardand the controller can adopt the prior art, such as the prior art givenin the background, and will not be further described herein.

In the present embodiment, waterproof rings are disposed between thelamp strips 154 and the lamp holes 114. When the lamp strips areinserted into the lamp holes, the waterproof rings are pressed so thatthe lamp strips, the waterproof rings and the lamp holes are tightlymatched to play a role of water prevention. Thus, when theself-balancing scooter of the present invention is used on a rainy day,rainwater is prevented from entering the scooter body from the lampholes.

In the present embodiment, the waterproof rings are made of rubbermaterial, and have good elasticity. Of course, the waterproof rings canalso be made of other materials.

Further, the waterproof rings and the lamp strips are bonded throughglue and the waterproof rings and the edges of the lamp holes are bondedthrough the glue. A sealing effect is better.

In the present embodiment, the waterproof rings are sleeved on the lampstrips to realize a waterproof effect. Specifically, the waterproofrings are provided with placing grooves for placing the lamp strips. Thewaterproof rings are sleeved on the lamp strips. The waterproof ringsare sleeved on the lamp strips to realize a good waterproof effect. Ofcourse, the lamp strips and the lamp holes can also be directly bondedthrough the glue to realize sealing and water prevention. However, insuch arrangement, when the self-balancing scooter is greatly vibratedduring rotation, the glue is easy to crack, causing that waterprevention is impossible. In the present embodiment, the waterproofrings have elasticity, and generate deformation under vibration, so thatthe waterproof effect is still provided. In addition, in the presentembodiment, the waterproof rings can also be sleeved on the lamp holes.For example, annular grooves for placing the edges of the lamp holes areformed at the edges of the waterproof rings. The edges of the waterproofrings are clamped to the edges of the lamp holes. Then, the lamp stripsare inserted into the lamp holes and matched with the waterproof rings.When the lamp strips are inserted into the lamp holes, the lamp stripsare pressed and fitted through the waterproof rings to realize a goodwaterproof effect. The waterproof effect can also be achieved.

In the present embodiment, the waterproof rings can also be disposed onindicating strips, so as to realize water prevention for the positionsin a lamp cover and an indicating lamp.

In the present embodiment, the self-balancing scooter further comprisesan indicating lamp electrically connected to the power supply 300.Specifically, the indicating lamp is disposed on an indicating lampplate 11. The scooter body 100 further comprises a lamp cover 160. Thelamp cover 160 is used to protect the indicating lamp. Specifically, thelamp cover 160 covers an outer side of the indicating lamp plate 11, andlimits and protects the indicating lamp plate 11. The indicating lamp isdisposed at the end portion of the middle of the scooter body. In thepresent embodiment, the end portion of the scooter body faces a user(when the user uses the self-balancing scooter), and the lamp covercovers the indicating lamp. The indicating lamp comprises at least twolamp beads. The power condition of the power supply is displayedaccording to the quantity of the lamp beads. The lamp cover comprises atleast two light transmitting indicating strips 161. The quantity of theindicating strips is identical with the quantity of the lamp beads. Eachof the indicating strips is provided with one of the lamp beads.

In the present embodiment, the indicating lamp used to indicate thepower state of the power supply is disposed in the middle of the scooterbody, and is covered by the lamp cover. The lamp beads on the indicatinglamp are respectively disposed on the indicating strips of the lampcover, so that light emitted by the lamp beads is emitted outwardsthrough the indicating strips to facilitate observation by the user.Moreover, at least two indicating strips are disposed in the presentinvention. Each indicating strip is matched with one lamp bead. When allthe lamp beads emit light, it indicates that the power is sufficient.When the quantity of the lamp beads that emit light is graduallydecreased, it indicates that the power of the power supply is decreased.Thus, the user can judge the power state of the power supply only byobserving the quantity of the indicating strips that emit light, therebygreatly facilitating the use of the user.

In the present embodiment, the upper shell 110 is provided withindicating holes 115 used to place the indicating strips. The quantityof the indicating holes 115 is identical with the quantity of theindicating strips 161. When the indicating strips of the lamp cover areinserted into the indicating holes, the indicating strips are matchedwith the upper shell and are limited, so as to play a further limitingand fixing role on the lamp cover.

Further, the lamp cover 160 is fixed to the middle shell 120 through thescrew. The screw is firm in fixation and convenient in installation anddisassembly. In this way, the middle shell and the upper shell arefurther connected together, thereby further increasing connectionstrength between the upper shell and the middle shell. Specifically, byreferring to FIG. 5, the lamp cover is provided with a lamp cover screwstud 162 used to penetrate through the screw to realize screwingfixation.

In the present embodiment, two lamp covers are disposed, respectivelyfixed to the first middle shell and the second middle shell and aredisposed symmetrically. Correspondingly, two indicating lamp plates 12are disposed, and are symmetrically installed and fixed on the firstmiddle shell and the second middle shell. Such arrangement is moreconvenient for the user to know the power state of the power supply byobserving the quantity of the indicating strips. This is a preferredmanner for disposing the lamp covers and the lamp beads in the presentembodiment. Of course, only one lampshade can also be disposed.

The size of the middle of each indicating strip is larger than the sizesof both ends of each indicating strip. The middle is configured to belarge, and light emitting intensity is large, so that the user observesmore conveniently.

The indicating strips are disposed in parallel. Such arrangementprevents the indicating strips from crossing each other. Once theindicating strips are crossed with each other, it is inconvenient forthe user to distinguish the quantity of the indicating strips.

The indicating strips are arc structures. The indicating strips of thearc structures have better display effect. Of course, the indicatingstrips can also be configured into other structures, such asstrip-shaped structures.

In the present embodiment, the waterproof rings can also be disposed onthe indicating strips, so as to realize water prevention for thepositions in the lamp cover and the indicating lamp.

For example, the waterproof rings are also disposed between the lampstrips 161 and indicating lamp holes 115. When the lamp strips areinserted into the indicating lamp holes, the waterproof rings arepressed so that the lamp strips, the waterproof rings and the indicatinglamp holes are tightly matched to play a role of water prevention. Thus,when the self-balancing scooter of the present invention is used on therainy day, rainwater is prevented from entering the scooter body fromthe indicating lamp holes.

In the present embodiment, the waterproof rings are made of rubbermaterial, and have good elasticity. Of course, the waterproof rings canalso be made of other materials.

Further, the waterproof rings and the lamp strips are bonded throughglue and the waterproof rings and the edges of the lamp holes are bondedthrough the glue. A sealing effect is better.

In the present embodiment, the waterproof rings are sleeved on theindicating strips to realize a waterproof effect. Specifically, thewaterproof rings are provided with placing grooves for placing theindicating strips. The waterproof rings are sleeved on the indicatingstrips. The waterproof rings are sleeved on the indicating strips torealize a good waterproof effect. Of course, the indicating strips andthe indicating lamp holes can also be directly bonded through the glueto realize sealing and water prevention. However, in such arrangement,when the self-balancing scooter is greatly vibrated during rotation, theglue is easy to crack, causing that water prevention is impossible. Inthe present embodiment, the waterproof rings have elasticity, andgenerate deformation under vibration, so that the waterproof effect isstill provided. In addition, in the present embodiment, the waterproofrings can also be sleeved on the indicating lamp holes. For example,annular grooves for placing the edges of the indicating lamp holes areformed at the edges of the waterproof rings. The edges of the waterproofrings are clamped to the edges of the indicating lamp holes. Then, thelamp strips are inserted into the indicating lamp holes and matched withthe waterproof rings. When the indicating strips are inserted into theindicating lamp holes, the indicating strips are pressed and fittedthrough the waterproof rings to realize a good waterproof effect. Thewaterproof effect can also be achieved.

In the present embodiment, as shown in FIG. 7 and FIG. 8, the two pedals140 have the same structure and size, and are respectively disposed inthe pedal holes 113 of the first upper shell 111 and the second uppershell 112. Each pedal 140 comprises a first placing portion 141 used toplace a tiptoe position, a second placing portion 142 used to place aheel position, and a connecting portion 143 located between the firstplacing portion and the second placing portion. A length of theconnecting portion 143 is smaller than a length of the first placingportion, and smaller than a length of the second placing portion. Twonotches 144 are respectively formed in the first placing portion and thesecond placing portion at both ends of the connecting portion.

The upper shell 110 is provided with an extending portion 117 placed ina position of the notches 144. Because the user pedals front and rearend positions of the pedals mainly through tiptoes and heels when feetare placed on the pedals, the middles of the pedals are not pedaled bythe feet of the user. In the prior art, the pedals are integrallyconfigured into a rectangular structure. In this way, the middles of thepedals are greatly wasted, and large holes need to be formed in themiddle shell and the upper shell to place the pedals. In the presentinvention, the connecting portions in the middles of the pedals areconnected to the first placing portion and the second placing portionrespectively. The length of the connecting portion is smaller than thelength of the first placing portion, and smaller than the length of thesecond placing portion. Two notches are respectively formed in the firstplacing portion and the second placing portion at both ends of theconnecting portion. In this way, the sizes of the middles of the pedalsare greatly reduced. Meanwhile, the extending portion of the upper shellof the present invention is placed in the position of the notch of thepedal, thereby increasing an area of the upper shell and increasing theintensity of the upper shell. The middles of the pedals of the presentinvention are configured to be smaller than the front ends and the rearends. In this way, the feet of the user are still convenient to pedal,thereby saving materials and production cost of the pedals. Meanwhile,the intensity of the upper shell is increased through the extendingportion of the upper shell.

In the present embodiment, the first placing portion 141 and the secondplacing portion 142 are disposed symmetrically along the connectingportion 143. Symmetrical arrangement ensures that the first placingportion and the second placing portion bear uniform stress.

In the present embodiment, on outer surfaces of the pedals 140, a heightof the connecting portion is smaller than a height of the first placingportion, and smaller than a height of the second placing portion. Theheight of the connecting portion is configured to be smaller than theheight of the first placing portion and the height of the second placingportion, so as to prevent the connecting portion from protrudingoutwards and affecting the feet of the user for pedaling the pedals.

In the present embodiment, the notches 144 are arc structures. The arcstructures have high strength, and are firm and convenient in matching.

In the present embodiment, a plurality of spaced anti-slip strips 146are respectively disposed on the first placing portion and the secondplacing portion. The anti-slip strips are disposed to play an anti-sliprole.

In the present embodiment, one end of the connecting portion is close tothe middle of the scooter body, and the other end is close to one sideof the scooter body. A size of one end of the connecting portion closeto the middle of the scooter body is larger than a size of the otherend, and is gradually decreased. This is a specific manner for disposingthe pedals.

In the present embodiment, an extending edge is extended on the uppershell at the edge of the extending portion. When the pedals are placedinto the pedal holes, the edges of the pedals are fitted onto theextending edge. The pedals are fitted onto the extending edge of theupper shell, so that the upper shell and the pedals have better fixedconnection effect and higher strength.

In the present embodiment, the middle shell is provided with pedalgrooves 123 used to place the pedals, as shown in FIG. 3. The placinggrooves have a limiting role for the pedals. Meanwhile, compared with acase of directly forming holes in the middle shell to place the pedals,the present embodiment greatly increases the strength of the middleshell.

In the present embodiment, inner surfaces of the pedals are providedwith limiting rings 145. When the pedals are placed into the pedalgrooves, the limiting rings are fitted with side walls of the pedalgrooves. The limiting rings are matched with the pedal grooves tofurther increase firmness of fixed connection between the pedals and themiddle shell.

In the present embodiment, a plurality of crossed reinforcing ribs 148are disposed on the pedals in the limiting rings. The reinforcing ribsare disposed to increase the strength of the pedals.

In the present embodiment, the self-balancing scooter further comprisestwo fixing brackets 700. The fixing brackets 700 are respectivelyinstalled and fixed on both sides of the scooter body, i.e., disposednear the two wheels. In the present embodiment, fixing blocks arelimited to the fixing brackets. Positions of both ends of each fixingbracket are used to install and fix two blocking elements 710 and twomatching elements 720. The matching elements have a role of limiting theblocking elements to ensure that the blocking elements are stablylimited in the fixing brackets. In the present embodiment, triggerelements 147 are disposed on bottom surfaces of the pedals 140 inpositions corresponding to the blocking elements. When the user pedalsthe pedals 140 and applies a force to the pedals, the pedals trigger theblocking elements through the trigger elements 147 so that the stressedblocking element is in a combining state. Not only the hub motors arestarted to operate, but also a stressed condition of the stressedblocking element is analyzed through the circuit board and thecontroller. Based on this, speed and balance of the self-balancingscooter are controlled so that the user conveniently controls theself-balancing scooter.

The trigger elements 147 are disposed on both sides of one notch 144 ofthe pedals, i.e., located at one end of the first placing portion andone end of the second placing portion. In this way, the trigger elementsare disposed in corner positions. Thus, when the pedals are pedaled bythe user, the connecting portion is used as a rotating shaft to controlthe pedal, so as to control a cooperation relationship between thetrigger elements and the blocking elements on the pedals.

A drivingmechanism is disposed in the middle of the scooter body, and portions ofthe upper shell and the lower shell in the middle of the scooter bodyare used to cover the driving mechanism without needing large strength,so that an arc depression adapted to the scooter body structure isdisposed in the middle position of the lower shell in the presentinvention. In this way, the size of the middle of the scooter body isdecreased. Not only the user conveniently holds the scooter body withhands, but also a height from the middle of the scooter body to theground is increased relatively, so as to better prevent theself-balancing scooter from touching an obstacle during running. Inaddition, the horizontal strip-shaped ribs are disposed at thedepression in the present invention. On one hand, because the depressionis disposed, the strength of the middle of the lower shell is greatlydecreased, while in the present invention, the strip-shaped ribs aredisposed to increase the strength of the depression position. On theother hand, the strip-shaped ribs are disposed to increase a frictionalforce, so that the user conveniently holds the middle of theself-balancing scooter with hands.

Heights of the strip-shaped ribs 116 are lower than the height of thedepression. In this way, the strip-shaped ribs are prevented fromprotruding out of the depression. In this way, a distance from themiddle of the self-balancing scooter to the running ground is longer, soas to facilitate the self-balancing scooter to run and effectivelyprevent the self-balancing scooter from touching the obstacle duringrunning.

A width of the depression 133 is gradually decreased from the middle ofthe lower shell to positions of both sides. Such arrangement ensuresthat the distance from the middle position located below the scooterbody to the ground is longer and the effect of preventing theself-balancing scooter from touching the obstacle is better.

Further, the depression 133 on the lower shell 130 extends to the sideportion of the upper shell 110, and the strip-shaped ribs 116 are alsodisposed on the upper shell 110 at the extending position of thedepression of the lower shell. The depression extends to portion of theupper shell. In this way, the user holds the self-balancing scooter withhands more conveniently. In a holding process, the hands of the userhold the middle position of the lower shell. Thumb portions and middlefinger portions extend to the middle position of the upper shell. Inthis way, the strip-shaped ribs are also disposed in the middle positionof the upper shell so that the user holds the self-balancing scooterwith hands more conveniently.

Sizes of the positions in which the strip-shaped ribs 116 are disposedon the upper shell 110 are smaller than sizes of the positions in whichthe strip-shaped ribs are disposed on the lower shell 130. Sucharrangement ensures that the strip-shaped ribs fit hand shapes of theuser.

The sizes of the positions in which the strip-shaped ribs are disposedon the scooter body are gradually increased from the middle position tothe positions of both sides of the strip-shaped ribs. Such arrangementensures that the position closer to the middle has a larger height fromthe ground in the self-balancing scooter. Thus, the effect of preventingthe self-balancing scooter from touching the obstacle is better.

Top surfaces of the strip-shaped ribs are configured into arcstructures. The arc structures are convenient for the user to hold andavoid injuring the hands of the user.
